Hibrenate clustered cache on Infinispan

Hibernate ORM
1

Hi. I’m trying to builld L2 cache in application, based on Infinispan. Also one of requirements is ability to horizontal scaling. I added jgroup configuration to my Infinispan configuration, but faced with error, that now i need to implement marshalling for internal Hibernate entities like BasicCacheKeyImplementation, StandardCacheEntryImpl, CollectionCacheEntry etc.

Because it throws exceptions like “No marshaller registered for object of Java type org.hibernate.cache.internal.BasicCacheKeyImplementation”

At the same time, i don’t undertand - how i can marshall and unmarshall internal entity CollectionCacheEntry - there is no information to get CollectionPersister on unmarshalling

Is there some error in my configuration? Or it is correct way of working clustered cache?

Besrt regards

Hey. I can’t personally help you implement a cache provider, but I can recommend that you don’t try that :slight_smile:

Are you aware Infinispan provides such a cache provider?

https://docs.jboss.org/hibernate/orm/7.0/userguide/html_single/Hibernate_User_Guide.html#caching-provider-infinispan
https://infinispan.org/docs/stable/titles/integrating/integrating.html#integrating_jpa_hibernate

Their documentation seems slightly out of date, but I’m pretty sure they support (much) more recent versions of Hibernate. Probably up to 6.6.

Might be worth a try before reinventing the wheel :slight_smile:

Apparently here’s the up-to-date documentation: Hibernate second-level caching (2LC)

I’ve done everything by this guide. But it targeted to create local cache and save it in memory. But when i turn on clustering feature, i faced with internal Hibernate entities. E.g.

org.hibernate.sql.results.graph.entity.internal.EntityInitializerImpl
Method void putInCache, line 1535 pushes cacheEntry (StandardCacheEntryImpl) to cache and then distributed cache should marshall it to send another node. And then Node2 should unmarshall it to StandardCacheEntryImpl also.

Thanks

I found solution. When used cluster on Hibernate Entities - you should use JBossMarshaller. Another way is very painful
